Changing the faulty disk

[Suresh_28]

We are having a HP 9000 running Hp-ux 11.0. One of the disk on vg04 failed. What are the necessary steps i need to carry out in changing the new hard disk on vg04.

Thanks

Being that this is a LVM disk. Follow the procedure for either mirrored non-root LVM disk or non-mirrored non-root LVM disk in this document

If the disk is hot swapable, then replace the disk online with a new one and do:
# vgcfgrestore -n /dev/vg04 /dev/dsk/cxtydz

This will restore the VG information to the disk. You need to then find out the file systems which was holding by the failed HDD, 'newfs' those file systems and restore data from backup.

Hi:

The procedure varies slightly depending on whether or not you are mirroring and whether or not the disk is hot swappable. See the LVM chapter (#16) in the Software Recovery Handbook:
